Abstract
Procedure for the preparation, of new benzofuran derivatives of the general formula I, **(See formula)** in which R1 means hydrogen, a halogen atom up to the atomic number 35, an alkyl group or an alkoxy group with, each time, 2 carbon atoms at most or the nitro group, R2 stands for hydrogen, a halogen atom up to atomic number 35, an alkyl group or an alkoxy group with each having 2 carbon atoms at most, R3 means an alkyl group with 4 carbon atoms at most and R4 and R5 each signify an alkyl group having 4 carbon atoms at most or both signify together with the adjacent nitrogen atom, -NR4R5, the piperidine or morpholinic 1-pyrrolidinyl group, and its addition salts with inorganic and organic acids, characterized in that an ester suitable for the reaction of a compound of the general formula II, **(See formula)** in which Rl, R2 and R3 have the significance indicated under formula I, it is reacted with a compound of the general formula III **(See formula)** in which R4 and R5 have the significance indicated under formula I, and if desired, the benzofuran derivative obtained from the general formula I is transformed into an adoption salt with an inorganic or organic acid.
